Okay so after I get done peeing I have this burning sensation and I'm kinda spotting.This has been going on for about 5 days now. My boyfriend thinks I am pregnant because today my boobs started hurting really badly but I already started my period a little over a week ago. I have a doctors appointment tomorrow at 1 and my mom's going with me but she doesn't know that I'm not a virgin anymore. I know It's sad that I'm almost 18 and I still can't tell her. Could I be pregnant or have a UTI, or both? Help mee.
